ADOLPH H. BAUER, OF NEW YORK, N. Y.

CARD SYSTEM.

Application filedJ'uly 5, 1913.

To all whom it may concern:

Be it known that I, ADOLII-I H. BAUER, a citizen of the United States, and a resident of the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Card Systems, of which the following is a specification.

This invention relates to card systems and has for its primary object the devising of means whereby cards are arranged in sequence in suitable manner to expose a portion of each card at all times, which portion may contain an index or other desired designation, and whereby the cards may be shifted to expose the body portion of any card to adapt it to be read, written upon or otherwise used without disarranging the other cards and whereby one or more cards may be withdrawn from the set or inserted at any place in the set without interfering with the order and arrangement of the other cards.

The various other objects of the invention will be more fully set forth in the following description of one form of a device embodying the invention which consists in the new and novel features of construction and combination of parts hereinafter set forth and claimed.

In the preferred embodiment of my invention the cards are pivotally mounted from one corner in detachable engagement upon a common pivot in suitably spaced relationto permit the upper portion of each card to be exposed and stops are provided upon each card to prevent the adjacent card below from encroaching upon the space but permitting the cards to be swung about the common center to expose any card.

Referring to the drawings forming part of this application, Figure 1 is plan view of a number of, cards forming a unit of the system. Fig. 2 is a sectional view of a set of units detachably secured upon a support. Fig. 3 is a plan view of several assembled cards showing a modified formof stop. Fig.

4c is a fragmental plan view of a support for the cards and several cards showing a modified form of stop and means for holding the cards down upon the support. Fig. 5 is a fragmental sectional view of a card showing another modified form of stop, and Fig. 6 is a fragmental perspective view of a Specification of Letters Patent.

and may be printed in any suitable manner i for the purposes intended. The cards have perforations 6 formed in their upper left hand corners, which are formed open at one portion by means of the comparatively narrow slots 0. r A support d of suitable sheet material as cardboard, aluminum and the like, provides a support for the cards and a post 6 is secured in the support for mounting the cards thereon. It is preferably in the form of a strip of comparatively thin metal to permit it to be passed through the slot 0 in the card when the card is removed or inserted.

The post 6 preferably constitutes one leg of a staple-like member having its other leg 7 secured in the support at a suitable point to provide a stop for the first or uppermost card of the set of cards a, and having the yoke 9 connecting the legs serving as a head for retaining the cards upon their pivotal post 6. The staple-like post and stop pass through the support and may be clenched or riveted on therear side or fastened in any other usual and well-known manner.

Stops are provided'one for each of the cards. These may be of various constructions and may be placed at various positions upon the cards. They serve to hold consecutive cards from coinciding throughout and thereby permit a uniform space being eX- posed to view upon each card.

In Fig. 1 the stops it are formed by slitting each card from the outer side edge upward and rearward forming a V-shaped tab. This tab overlaps the card below and serves as a stop to prevent the engaged card from passing. The height of the slit in this instance determines the space exposed on the card above the stop.

In Fig. 4: the stop 71, is formed by slitting the card from the lower edge near the outer side edge upward and outward thereby forming a V shaped top which overlaps the adjacent card to form a stop therefor In this type of stop the extentto which the cut is made to the outer side edge of the card also determines the space provided between adjacent cards along the upper edge.

The stop shown in Fig. 6 is placed in a position upon the card similar to that shown in Fig. 1. It is made in the form of a metal clip. The body portion 1' of this stop is folded over the edge of the card and the folded sides pressed tightly to the card. For better securing it, rivets or other devices may be used. The tongue y is formed to extend from the body portion and is offset in order that an adjacent card may be held be-' neath it similarly to the tabs already described.

, The stop 71 shown in Fig. 3 resembles an ordinary metal staple passed through the card and clenched in the usual way on the rear side. This construction has the advantage that it may be placed comparatively near the pivotal point of the card. This form of stop does not'overlap the adjacent card but on account of being placed near the pivotal point there is little danger that the card held by it will he accidentally lifted high enough during manipulationof the system to bring it over the stop and thus encroach upon the space intended to be left exposed. V v

The stop shown in Fig. 5 presents another construction that'may be placed near the pivot of the cards. This is formed of a folded strip of metal forming a clip is which may be secured over the edge of the card by simple pressure or by rivets, as shown,

, or similar devices.

'It is obvious that many other forms of stops may beused than those shown.

The cards are preferably held at their free ends within a circumferential groove Z which maybe formed as shown in Fig. 1 by securing a circularstrip of metal 02. upon the support d which may also be inv the form of a semicircle as shown. The strip is offset to form a space between its inner edge and the support 0? within which the lower outer ends of the cards are confined butwith suflicient freedom to permit them to be turned about their pivots.

Fig. 4 shows'a different manner of holding the free ends of the cards down upon the supportsand a different pivotal connection for the cards. Here a'semicircularly bent rod 0 is secured at either end .to the support and the tab corners of the cards are placed beneath it with the tabs overlapping it. This rod or wire holds the cards down upon the support, and at the same time, by having part of the card below the rod and another part above or over the rod makesit' impossible for; an adjacent card to pass the tab and encroach upon the space intended to be exposed. A strip of metal p is secured to the support (i having an upstanding circular flange 9 against which the tab corners of the cards abut thereby. confining the cards to a circular .them which engage the headed posts 8.

known loose leaf book devices for receiving the leaves and no further description of it is deemed necessary" except that it maybe opened at the split joint w to remove or 1nsert a unit of the system which includes a support dwith the cards carried by it. The

' units may be shifted to either leg of the post in the ordinary manner ,of loose leaf books.

In the operation of my invention as illustrated in Fig.1 the cards are mounted on the post a by passing it through the open.

slot 0 in the card until the perforation?) engages the post; the card isthen bulged up in the center temporarily to foreshorten it to permit the lower free end to be slipped in the groove Z. The card is then permitted to flatten out and is placed in proper position against the stop of the adjacent card. In'this way the system is built upon the support d thus forming a unit. The exposed part of the cards may conveniently-be used for-an index thereby affording a continually exposed index, although it may be used for other purposes ifdesired. When the body of the card is to be read, written upon or otherwise used the card is held fixed and drawn from the groove and then revolved until the slot 0 is brought in line with the post 6, in which position it is easily withdrawn from the post. When inserting a card the procedure just described is reversed, the cards being first manipulated to open a space for the card 'to be inserted. When removing a card in the form of construction shown in Fig. 4 the card is removed first from the post .9 by bulging the card upward. It is then easily slipped from the rod 0 to clear the tab therefrom by properly swinging it about that corner. The insertion of a card is effected by substantially reversing the steps described.

I have shown only some of the forms of" construction embodying my invention, and

it is obvious that various changes within the skill of the mechanic may be made therein without departing from the spirit of the invention, provided the means set forth in the following claims are employed.

Having thus described my invention I claim 1. In a device of the character described, a number of cards placed one upon the other, a support for the cards, means secured to the support for pivotally engaging the cards, and stops extending one from each card to provide an abutment for the adjacent card when in normal position to provide a continually visible portion on each card and adapting the said adjacent card to be swung about the said means away from its stop thereby exposing the card to view containing the stop from which the adjacent card is moved.

2. In a device of the character described, a number of cards placed one upon the other, a support for the cards, means secured to the support for holding the cards in detachable pivotal engagement and stops extending one "from each card to provide an abutment for the adjacent card when in normal position to provide a continually visible portion on each card and adapting the said adjacent card to be swung about the said means away from its stop thereby exposing the card to view containing the stop from which the adjacent card is moved.

3. In a device of the character described, a number of cards placed one upon the other and provided with open slots, a support for the cards, a post extending from the sup port for engaging the cards through the open slots in pivotal engagement, and stops one on each card affording an abutment for the adjacent card to provide a continually visible portion on each card and adapting the said adjacent card to be swung about the said post away from its stop to thereby ex pose the card to view containing the stop from which the adjacent card is moved.

4. In a device of the character described, a number of cards placed one upon the other, a support for the cards, means secured to the support for pivotally engaging the cards, stops extending one from each card to provide an abutment for the adjacent card when Copies of this patent may be obtained for five cents in normal position to provide a continually visible portion on each card and adapting the said adjacent card to be swung about the said means away from its stop thereby exposing the card to view containing the stop from which the adjacent card is moved, and a circular guide for engaging free ends of the cards to hold them upon the support.

5. In a device of the character described, a number of cards placed one upon the other, a support for the cards, means secured to the support for pivotally engaging the cards, a circular guide secured to the support in spaced relation therewith for holding the cards within said space, said guide adapted to guide the outer corner of each card in its movement about the pivot, and stops one on each card extending above said space to provide an abutment for the adjacent card when in normal position to provide a continually visible portion on each card and adapting the said adjacent card to be swung about the said means away from its stop thereby exposing the card to view containing the stop from which the adjacent card is moved.

6. In a device of the character described, a number of cards placed one upon the other, a support for the cards having an eyelet formed therein, means secured to the support for pivotally engaging the cards, stops extending one from each card to provide an abutment for the adjacent card when in normal position to provide a continually visible portion on each card and adapting the said adjacent card to be swung about the said means away from its stop thereby exposing the card to view containing the stop from which the adjacent card is moved, and a bent post for engaging said support through the eyelet therein in slidable relation therewith, said post having a joint adapted for opening it to permit the support to be removed or inserted.
